BRACELET nnn HOOK.

Applica'tionfiledMay 20, 1927. Serial No. 192,915.

This invention relates to a bracelet end hook of'the type secured to the ends of an ornamental link chain to attach the same to the bails or lugs of a wrist watch, and this invention has for its object to provide in such a construction a pivoted hook closing tongue which has portions readily accessible for manually swinging the tongue on its pivot to permit the hook to engage or be disengaged from the bail of a wrist watch.

A still further object of the invention is to provide a pivoted tongue having a portion extending along the outer surface of the back wall of the body portion of the end hook with wings for gripping the side walls of the hook to retain the tongue in closed position.

.A still further object of the invention is to so pivot the tongue that the pivot pin will be prevented from endways movement by the side walls of the hook thus eliminating the necessity of enlarging the ends of the pin for this purpose. r

. The invention further consists in the provision of ears on the back wall and also integral ears on the tongue through which the pivot pin passes to mount the tongue in its operative position. I

With these and other objects in view the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. I

.In the accompanying drawings:

Figure 6 is a sectional view similar to Fig ure 5 showing the-back wall folded to its closed position.

. Figure 7 is a section on line 77 of Fig ure 6.

Figure 8 is section on line 8-8 of Fig ure 6.

Figure 9 is a central sectional side view of the tongue in open position illustrating in dotted lines the bails or lugs oi? a wrist watch entering the opening of the hook. I

Figure 10. is a side elevation of the hook portion of the watch showing the tongue in the position that it assumes when the hook is beingdetached from the watch bails.

It is found in practice desirable to provide a hook for attaching a watch bracelet to the bails of a wrist watch with a pivoted hook closing tongue which may be easily manipulated for attaching or detachingpurposes and yet one which will be retained in its closed position and prevent inadvertent .or accidental opening to permit detachment of the watch therefrom. It is further found of advantage to provide such a construction which is strong and durable and so constructed that the same may be formed by the minimum number of hand operations and to accomplish this I have pivoted a tongue on the back wall of the body of the hook with a pivot pin so located that it is prevented from endwise movement by the side walls of the body of the hook, thus eliminating the necessity of enlarging the heads of the pivot pin to hold the same'against endways movement and further, I have so mounted this tongue that no springs are necessary for its operation, it being held in closed position by frictional engagement with the side walls of the body of the hook and the following is a detailed description of the present embodiment of this invention and illustrating one con struction by which these advantageous results may be accomplished: v

With reference to the drawings, 10 designates the top wall of the body portion of the end hook which is provided with side walls 1]] and a backwall 12 formed by folding an extended portion of the top wall back upon itself, as illustrated in Figure 5, the hook proper .is also formed by extending the top wall and foldin it into a hook 13 to receive the bail 14; o? a wrist watch 15. In order to close the opening 16 of the hook, I have pivotally mounted a tongue 17 which has integral ears 18 cut and bent from the stock till of the tongue with piercings 19 to receive the pivot pin 22 which also passes through cars 20 carried by the back wall 12 to pivotally mount the tongue in position in the body.

The pivot pin 22 is positioned through both cars 18 on the tongue and 20 on the back wall before the back wall 12 is folded into final position as illustrated in Figure 6 folded slightly over the back wall to retain it in finished position. One end of the tongue 24 engages beneath the end of the hook 13 to close the opening 16 thereto'and the opposite end 25 of this tongue extends along the outer surface of the back wall 12 and has wings 26 to frictionally engage the outer surface of the side walls 12 with portions of the stock 27 deflected outwardly to form .knobs to be manually engaged for swinging the tongue on its pivot to open the hook.

The deflection of the sheet stock to form knobs causes recesses 28 on the inner surface of the wings which receive the detents 29 pressed outwardly from the side walls 11 and thus the tongue is securely friotionally retained in its closed position by the snapping of the wings 26 over the detents 29.

In doubling the portion or back wall 12 back upon itself an opening or loop 30 is formed to receive one of the connecting links of the bracelet 31, as illustrated in Figure 1.

I have provided a hook which is strong and durable in its construction and one which may be made with the minimum hand work to reduce its cost of production.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I re-. serve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

A bracelet end hook comprising a body having front, back and side walls, the front wall being extended and formed into a hook, a tongue pivoted in said body intermediate its ends and of a length to have one end close said hook, the opposite end of the tongue extending along said back wall with portions engaging the outer surface of said side walls to be manually grasped to swing saidtongue on its pivot to open said hook.

2. A bracelet end hook comprising a body having front, back and side walls, the front wall being extended and formed into a hook, a tongue pivoted in said body intermediate its ends and of a length to have one end close said hook, the opposite end of the tongue extending along said back wall with portions engaging the outer surface of said side walls to be manually grasped to swing said tongue on its pivot to open said hook and means between said tongue and side wall for frictionally retaining said tongue in closedposition.

3. A bracelet end hook comprising a body having front, back and side walls the front wall being extended and formed into hook shape, a tongue pivotedin said body positioned to close said hook and having a portion extending along saidv back wall with wings extending along theside wall of the body on the outer surface thereof when the hook isin closed position, detents onsaid side walls and recesses in said wings to receive said detents when the wings are snapped thereover to hold the tongue in closed position.
